GRAIN-BINDER.

SPECIFICATION forming part' of Letters Patent No. 481,974, dated September 6, 1892.

Application filed July l, 189].. Serial No. 399.436. (No model.)

T all 1072/0771/ it 71u01/ concern,.-

Be it known that I, GEORGE SCHUBERT, a citizen of the United States, residing at NValnut, in the county of Bosque and State of Texas, have invented certain new and useful Improvementsin Grain-Binders, of which the following is a specification.

My present invention has reference to a platform-binder in which the needle or cordcarrying arm is placed below the deck of the platform and the cord-tying mechanism is placed above the deck of the platform, and the needle being so arranged as to pass beneath the upper plate of an ordinary platform five or six inches in depth and to receive the grain and to compress the same without the assistance of any packers or specially-operated packing mechanism. I attain these olojects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of a harvesterplatform provided with my improvements. The front breast-plate and a portion of the upper oor of the platform are broken away, so as to show parts below in full lines. Fig. 2 is a front View of the inner portion of the machine. Fig. 3 is a stubble-end View of same. Fig. 4 is a similarview as that of Fig. 2, with the needle elevated. Fig. 5 is a sectional view on line 1 1 of Fig. 1, with thencedle partly elevated and with the free joint of the needle locked in position. Fig. 6 is a cross-section of the breast-plate on line 2 2 of Fig. 5, showing the belLcrank, spring, and hook J4 in position. Fig. 7 is a detail view of the spring, and Fig. 8 is a-detail View of the bell-crank. Fig. 9 is a sectional view on line 3 3 of Fig. 10 of the gear-wheel and its guide. Fig. 10 is a plan view of the gear-wheel and its guide. Fig. 11 is a plan View of a bearing carried by the bracket shown in Fig. 12. Figs. 13 and 14 are plan and side views of the binder-frame to support a part of the gearing. Fig. 15 is a View of the spring and stud to lock the free end of the needle in position. Fig. 16 is a detail View of the shaft carried by the pivoted bearing js. Figs. 17 and 18 are detail Views of the needle. Fig.

19 is a perspective View of the shoe, and Fig. 2O is a detail View of the bifurcated end of lever k7 and the spring carried by said lever. Referring to the drawings, A designates the platform. a designates its upper floor, and d its lower floor, braced apart by the strips d2, a3, and 0.4, the strip a4 forming the rear sill of the platform, while the strips a2 and as form the walls for the passage-way for the conveyer g. The lower platea is secured to thelower flange of the linger-bar A', andthe upper plate a is secured to the upper fiange of the fingerbar A. Said finger-bar A is provided with the usual guard-fingers A2 and an inner shoe A3. Said shoe A3 is provid ed with a vertical {iange A4 on its forward projecting end, as shown in Fig. 3. To said flange A4 is secured a post A5.

A6 designates a cross-bar framed to the post A5 and extending rearward with its free end a proper distance above the platform, as

shownin Figs. 2, 3, and 5. The inner or stubbleward ends of the finger-bar and platform are extended stubbleward a proper distance, so as to provide room for the mechanism hereinafter described. The stubbleward extension of the finger-bar A is provided with a vertical dan ge A7.

a is a iiange formed on the front edge of the stubbleward extension of the plate a and secured to the vertical flange A7.

B designates the binder-frame, provided with projections b2 and b3, by which it is secured to the linger-bar A and provided with arms or sleeves b and h', perforated to receive the shaftsf and f. The projection h3 is perforated at b4 near its end to provide a bearing for the front end of the shaft g to operate the conveyer. The rear end of the s aid shaft g finds its bearingin the strip a3. Thelower arm b of the binder-frame extends rearward, with its lower half b5 adjacent the hub of the needle and with its upper half cut away far enough to provide room for the passage of the sprocket-chain g3, as shown in Fig. 14, and is provided with a downward-projecting arm b adjacent the front side of the sprocket-chain g3, provided with flanges 57 and bs, by which the rear end is secured to the lower plate a. of the platform. The upper arm b extends nearly as far toward the rear as the lower arm b', and is also provided with a downward projection b9, to which is secured the stubble end of the front breast-plate A8. The grain ends of the breast-plates A8 and A9 are secured to the cross-bar A6.

IOO

Said lever 7J is pivoted near its center to the bracket J abreast the binder-frame B, extending upward and having its upper end bifurcated, as shown, with the arm h bent outward, as shown, so as to allow the pin 2 to enter when the gear-wheel I is rotated, and provided with a spring h2 to engage with the pin 2 and to hold the gearwheel Iin place and start said gear-wheel I, as hereinafter stated.

j designates a shaft, finding a bearing near its grainward end in the post A5 and provided with a bearing near its other end in the bracket j', which is secured to the binderframe B, as shown in Figs. 2 and 3. Said shaft j is provided with a collar f, secured thereto adjacent the stubbleward side of the post A5, and a bevel-pinion js, adjacent the grain side of the bracket j'. Said bracket j is provided with an inner arm jl. Said arm ,7'4 is bent stubbleward at its upper end, forming the projection j?.

jg is a web connecting the bracket j with the arm or projection j7 at t7'5. Said connection is made of sucient size to form a support or slide for the front or free end of the pivoted bearingjs. Said bearing 7'8 is pivoted to the projection j? by the set-screw js, with the free end j resting on the slide 7'5.

10 designates a shaft carried by the pivoted bearing js and provided with a pinion in position to engage with the gear-wheel I and having its rearward-projecting end flared or dovetailed, as shown at 8, and in position to engage with the guide 5 and a bevel-pinion t, secured on its forward-projecting end in position to be engaged and disengaged with the bevel-pinion j3, as hereinafter described.

f2 designates a crank formed on the forward-projecting end of the shaft f. Said crank is in position to receive the lower end of the connecting-rod t". Said shaft j'" projects through the arm b", and to its rearwardprojecting end and adjacent the projection b5 is secured the inner or first section f3 of the normally grainward extending jointed needle, and near the rear side of the slot g2 and to the free end of the section f3 is pivoted the section f'iof the needle, also projecting grainward when the needle is at rest, as shown in Figs. l and 2.

f5 designates a perforation formed near the lower edge of the section f3 and slightly in rear of the pivot f.

f8 designates a stud provided with a spring f7, said stud having the lower side of its free end beveled, as shown in Fig. l5, and is projected through the perforation f5 in the scction f3,with the flat springf7 extending stubbleward and secured to the section f3, as shown in dotted lines in Fig. 18.

ff designates a bar secured to the strip a2 and projecting rearward with its free end to near the rearsection f3 of the needle, with its free end rounded to near the same size of that of the study"s and with its upper side bcveled and located in line of movement of." the stud f8, as shown in Fig. 5.

f10 designates a block secnred'to the stri a2 to additionally secure the bar ff.

f is a slot cut in the inner portion of the heel of the second section f4 of the needle, as shown in Fig. 17, of sufficient size to allow the free end of the barfgto enter and operate the section f4 of the needle, as hereinafter described.

f12 is a perforation in the point of the needle to receive the usual cord.

f14 is a light plate secured on the strip a2to strengthen the upper end of the pivot of the bell-crank D2and extending to near the binder-frame, with its rear edge projecting partly over the block f1".

J J designate the compressors, each of which is provided with an eye near its upper end, by which the compressor is loosely secured on the shaft fand has its lower end curved to conform with the curvature of the sheaf.

J' J' designate coiled springs, each of which is rigidly secured with one end to a compressor J by a staple J2, with the end J.3 en tering a small perforation in the compressor. The other end of the spring is bent to one side (to the side of the coil next the breast-plate) and then turned at a right angle toward the breast-plate, so as to enter the slot J6 in the vertical flange L of the breast-plate A. For the rear compressor the hook J4 is turned rearward, and for the front compressor the hook J 4 is turned forward toward the breastplate A8. One or more of such compressors can be employed. Two are shown in the drawings.

J8 designates a bell-crank loosely pivoted on the free end of the coiled spring J'xbetween the end of the coil and the hool J4, with the longer arm J 5 extending downward adjacent the vertical ange L, and the arm J7 projecting horizontally and at a right angle from the ange L and of sufficient length to extend into the path of the discharging-arm K. The discharging-arm K is riveted to the bracket K', which is rigidly secured to the shaft f, by which the discharging-arm K is rotated. Said discharging-arm K is of ordinary construction and of proper length to dis-y charge the bound sheaf and is placed adjacent the eyes of the compressors J. The vertical ianges L of the breast-plates A8 and A9 are cut out at L5 to clear the shaft fand its fixtures, and having an offset at L', as shown in Figs. 1 and 5, for the purpose hereinafter described.

L2 designates a bracket loosely secured on the rear end of the shaftfby the pin L6,adja cent the rear compressorJ and provided with a flange on the lower end of its downward projection, to which is secured the rear or stubbleward end of the breast-plate A.

A10 is a breast-board secured to the stubble end of the breast-platesA8 and A9. The front breast-board for the breast-plate As is shown in dotted lines only in Fig. l. y

The operations are as follows: The mechanism is started by the butt-board D being moved in position, as seen in dotted lines in Fig. 1, by the conveyer, thereby drawing the rod h grainward, which in turn moves the up- -per end of the lever hl in the opposite direcymove in the opposite direction and causing it to engage with the bevel-pinion js, thus turning the gear-wheel I until the depression i3 comes again opposite the pinion t7, and the guide t5 engaging, with the projecting ende'8 of the sh aft '1110, thus drawing the pinion ilinward to the extent of the depression 3, and thereby disengaging the bevel-pinion if from the bevelpinion i72, which allows the gear-Wheel I to discontinue its rotation until again started by the lever k7, as heretofore described. The shaft j receives its motion from gearing of the harvester. (Not shown in the drawings.) The c onnection of the rod D4 with the bell-crank D2 is placed in the line joining the pivots of the bell-crank D2 and the connection of the rod the rod h will not operate the butt-board.

, Thus it will be seen that the rod h will hold the gear-wheel I in position untilstartedby said bell-crank. The shaft f 'is rocked by the gearwheel I through the crank f2, connecting-rod z", and wrist-pin t', and the rear section f3 of the needle being secured to the rock-shaft f. Said rock-shaft f' will operate the needle as follows: First moving the section f3, and the section f4, being in engagement with the bar f9 and pivoted to the section f 3 beyond the bar f, said bar ff will cause the section f4 to move in the position shown in Fig. 5, the two sections being locked in position by the stud f8, when the needle is in position to compress. the grain and deliver the cord to the knotvened out, as seen in Fig. 2 in dotted lines, by

the bar ff operating on the inner side of the slot f 14. The discharging-arm K is rotated by the shaft f. The compressor is loosely hinged on the shaftfand held in position by the spring J', the hook J4 of said spring` engaging in the slot J 6 in the breast-plate ange L. Said spri'ng J is of proper strength to impart to the compressor the proper amount of action or elasticity. The discharging-arm K comes in contact with the arm J7 of the bellcrank J8 at about the time the cord-tyingoperation is far enough advanced to dispense with the compressor, when the arm J7 will be depressed, and the arm J 5, resting against the flange L of the-breast-plate, will cause the hook J4 to withdraw fromv the slot J 6.-' Next,

.the discharging-arm K will move against the grain end of the spring J', and moving it stubbleward, thus moving the compressor IOC stubbleward and upward, so as to clear the passage for the discharge of the bound sheaf. At the time the sheaf is being discharged the grain end of the spring J arrives at the depression L of the vertical iange L, when the spring will move outward toward the depression L', and thus move from under the dischargingarm, and as soon as the discharging-arm has moved out of the way lthe said spring J will again be moved grainward by means of the weight of the compressor J until the hook J4 again engages the slot J 5, thus locking the compressor in position for the next operation. The operation of the other or forward compressor and dischargingarm is lthe same as the ones just described.
